A Long-Pulse, High Energy, Narrow-Band Width CO2 Laser for Doppler Wind LIDAR Applications

In this paper the realization is described of C02 laser with high energy (~ 10 J/pulse), long pulses (~ 2 ~s) and narrow bandwidth (~ 200 kHz), using suitable discharge device (Lumonics 602) and cavity configuration (modified self-filtering unstable resonator). The theoretical considerations which led to these choices are also discussed and the results obtained are shown
